What else can I help you with?
What does the difference in air presssure above and below a birds wing cause?
The difference in air pressure above and below a wing causes lift. The lift creates flight. The result is that birds fly.
What bird can lift the highest weight?
Birds do not lift weights.
How do birds' wings work to enable them to fly?
Birds' wings work by creating lift and thrust. The shape of the wing and the way air flows over and under it generate lift, allowing the bird to stay airborne. The flapping motion of the wings also creates thrust, propelling the bird forward. This combination of lift and thrust enables birds to fly.
Are birds wings flat for increasing lift?
If they were flat they would generate no lift and birds could not fly. Aeroplane wings are very similar in shape to bird wings - they are nearly flat underneath and convex on top.
Will a lorry with birds on it weigh the same if all the birds lift up in the air?
If the lorry contains the birds in a sealed container then the weight is unchanged. As they lift from their perches they must accelerate and the resultant downward force on the lorry will make it appear to weigh more for a very short time.
Which feather is important for flight?
The large one on a birds wings; they produce lift.
What special designs do birds have that enable them to fly?
Birds have hollow bones, and that makes them light enough for their wings to lift them off the ground. Also they have wings and lots of feathers, and they are shaped to give the bird lift so it can fly.
How do birds move in the air and on the ground?
Birds move in the air by flapping their wings to generate lift and propel themselves forward. On the ground, birds walk or hop using their legs and feet.
How many swans are lift?
swans the birds - approximitly 50,000 all over the world
The feathers of birds serve two primary functions?
lift for flight and conserving heat
Why do birds push the air downwards with their wings?
so they can gain lift so they can fly
What is the function of birds tail?
the function of a tail is to lift its body and to increase the speed of flight
